Unblocking a program in ZoneAlarm
In case a program was accidentally blocked by you or someone else using your computer, the ZoneAlarm program gives you an easy way to "unblock" it as a long term solution to your firewall woes. To unblock a program:

1. Right-click the ZoneAlarm icon in your system tray and select Restore ZoneAlarm Pro Control Center.
2. From the menu, select Program Control.
3. Now, click the Programs tab to access the list of applications that have either been granted or denied access to the Internet.
4. Make sure SwiftKit or Toolkit for RuneScape is allowed.
